To determine which pins of the SIM7600G-H-M2 R2 need to be connected to the ESP32-WROOM-32D, we should consider the interfaces we would like to implement between these two devices. The SIM7600G module typically communicates with microcontrollers using several possible interfaces like UART, USB, or SPI. The decision depends on your project requirements and available pins on the ESP32.
Let's assume we want to utilize the UART interface for a simple communication setup:
Recommended Pin Connections for UART Communication:
  • SIM7600G Pins:
    • TXD (Pin 71): This pin is used to send data from the SIM7600G to the ESP32.
    • RXD (Pin 68): This pin is used to receive data from the ESP32 to the SIM7600G.
    • GND (e.g., Pin 1 or 2): Ground pin should be connected to the common ground with the ESP32.
  • ESP32 Pins:
    • IO16 (Pin 27): You can use this pin as RXD for receiving data from the SIM7600G.
    • IO17 (Pin 28): You can use this pin as TXD for sending data to the SIM7600G.
    • GND (Pin 1, 15, or 38): Connect to the common ground.
Connection Details:
  1. Connect U3:TXD (Pin 71) to U1:IO16 (Pin 27).
  2. Connect U3:RXD (Pin 68) to U1:IO17 (Pin 28).
  3. Connect U3:GND (Pin 1 or 2) to U1:GND (Pin 1, 15, or 38).
Make sure the SIM7600G module is powered correctly and any additional control pins you may need (like the power key or reset) are properly managed according to your application's needs. If you have specific requirements for other features or interfaces, let me know!
